WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 414,665, dated November5, 1889.

Application filed April 25, 1889. Serial No. 308,559. (No model.)

To all whom it may concern:

Be it known that we, JOHN WILLIAM WIL- coX and JOHN WILLIAMS, citizensof the United States, residing at Smithville, in the county of Clay andState of Missouri, have invented certain new and useful Improvements inVagon-Brakes; and We do declare the following to be a full, clear, andexact description of the invention, such as will enro able othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of this I 5specification.

This invention, relating to wagon-brake levers, will first be describedin connection with the drawings, and then pointed out in the claim.

Figure 1 of the drawings is a side elevation, and Fig. 2 a transversevertical section.

' In the drawings,A represents abrake-lever fulcrunled at ct, and B thecurved rack in which it works on one side of a wagon.

C is a cleat made fast to one side of a wagon, and slot-ted at c, so asto receive therein both the curved rack andthe double-ended pawl D.

vE is a pin which passes through the leverhole of, cleatwhole c', andthe median transverse slot d of the pawl.

The rack B does not have the usual inclined teeth, but is provided withsuch as are perpendicular to the center of the circle of which it formsan are, the object being to allow the opposite ends of the pawl to lockwith equal facility.' The pawl D has an elongated vert-ical slot d',extending to the slot d, to receive the presser-pin G, which 4o isoperated by the spiral spring H, so as to assist gravity in holding thepawl D to the rack B. When the lever A is moved to one end of the slotd, the pin E presses the nearest end of the pawl into the rack, whilethe farther end rises therefrom. y

In driving a four-horse team the driver may ride one of his horses andwith a rope put thebrakes on and offv the wheels, said rope being usedto actuate the lever.

We are aware that a double-ended pivoted pawl working in a rack withperpendicular teeth is not new; but the construction of our pawl withthe two slots d d and the springpressed pin G working therein arebelieved to constitute a new feature and one which gives utility to thedevice.

We are acquainted with the brake described in Patent No. 383,187 butthat is specially7 applicable to endless cables and requires a grip tooperate the lever, while ours is specially applicable to wagons. s Ithas not our slots d d', by which the pawl D automatically adjusts itselfto the rack and to the spring-pin G, which constitute the new featuresof our invention. Again, the purpose of our pawl is different from thatdescribed in Patent No. 383,187,

vthe purpose of that being to rotate a gearwheel, while ours is to locka ground-wheel.

Vhat We desire to protect by Letters Patent is- In brake-levermechanism, a middle-pivoted double pawl D, provided with slots d d andspring-pin G, whereby the pawl automatically changes its position withrespect to the rack and spring-pin, as described.

In testimony whereof we affix our signatures in presence of twowitnesses.
